The Role of Attentional Bias Toward Negative Emotional Information and Social Anxiety in Problematic Social Media Use.

The current study aimed to analyze whether individuals with problematic social media use (PSMU) demonstrate attentional bias (AB) toward negative emotional information and determine the relationships among the severity of PSMU, social anxiety, and negative AB. Sixty participants were divided into problematic and normal use groups according to their scores on the Bergen Social Media Addiction Scale (BSMAS). The BSMAS and Interaction Anxiety Scale were adopted to measure the severity of PSMU and social anxiety, respectively. An emotional Stroop task and a visual dot-probe task (DPT) were used to assess AB toward negative emotional expressions. Relationships among the severity of PSMU, social anxiety, and negative AB were investigated using Pearson's correlation coefficient. Results showed that individuals with PSMU demonstrated AB toward negative emotional information in the emotional DPT but not in the emotional Stroop task. AB toward negative emotional information was positively correlated with the severity of PSMU and social anxiety in the emotional DPT. Findings support the key role of negative AB and social anxiety in individuals with PSMU, suggesting that more attention be paid to negative AB and social anxiety for the prevention and treatment of PSMU.

The Impact of COVID-19 on the Acute Stroke Care Pathway: Looking Beyond the Short Term

Background Early in the pandemic, coronavirus disease 2019 (COVID-19) had been reported with significant impact on the stroke care pathway. Meanwhile, the mid/long-term consequence of treatment efficiency and effectiveness of the acute stroke pathway still remains unknown. Methods A comprehensive retrospective analysis was conducted on the acute stroke care pathway parameters in a stroke unit in Chongqing, Southwest China. A total of 1492 patients were involved in this study, of whom 634 patients (42.5%) were included during the COVID-19 pandemic, 858 patients (57.5%) included during the similar period of 2019. We collected demographic and clinical characteristics, clinical outcome as the treatment efficiency and effectiveness indicators of the acute stroke pathway. Results Compared to the same period in 2019, there were 2.8% fewer transient ischemic attack (TIA) patients, while 9.9% more acute ischemic stroke patients in 2020. In addition, patients had significantly higher National Institutes of Health Stroke Scale (NIHSS) scores (P = 0.002) and hospital mortality (P = 0.004) during the pandemic. The median door-CT time (P < 0.001) and emergency stay (P < 0.001) of acute stroke were also remarkably increased during the pandemic. The proportion of patients with intravenous thrombolysis (IVT) was significantly lower (P < 0.001), while the mechanical thrombectomy (MET) was remarkably higher (P = 0.042) in the pandemic group. Moreover, the IVT was significantly delayed during the pandemic (door-needle time: P = 0.001). Conclusion The COVID-19 outbreak did not reduce the willingness of the acute stroke patient to seek medical help. Benefited from adjustments of stroke procedure in response to the COVID-19 pandemic, no significant reduction was observed in the reperfusion success of the acute stroke care pathway. However, more medical resources need to be invested into the acute stroke care pathway to prevent serious consequences of undiagnosed and untreated strokes.
